Take inner ring needle roller bearing how to realize low noise processing

Needle roller bearings with inner circle how to realize low noise processing source: this website the author: the administrator to release time: 2017 - 06 - 15 08:10:09 views: 0 needle roller bearings with inner circle how to realize low noise processing for bearing products, believe that everyone should not unfamiliar, as machinery and equipment parts, in order to the normal operation, the use of the various series of bearing is very common. Different types of bearing products in use process, want to work its operation to achieve low noise, using precision parts, maintain accurate processing to achieve. Now, let's look at how the inner ring needle roller bearing processing, make its noise can be down to low, so to equipment and the product is good. To achieve low noise requirements, with the inner ring needle roller bearing inner and outer ring raceway in end milling process should be appropriately extended light grinding time and provided a basis for the raceway superfinishing. Superfinishing should be a more than ordinary products. Inner ring surface of the guard in end milling process should choose abrasive particle size 120 # of grinding wheel, grinding time of light not less than 4 s. The surface roughness Ra value should be with the inner raceway, so that the dynamic pressure oil film formation. With roller surface shader self-agreement should not be less than 90%. Tapered roller, in addition to outside diameter size accuracy and geometric accuracy and surface quality shall meet the technical conditions of the corresponding precision grade, needle roller bearing ball base surface roughness Ra value is not greater than zero. 321 xm, and the period of the same is true of diameter size. In addition, the cage of contraction, under the premise that does not affect the bearing rotating flexibility to tighten. Through the description of the above, should all superfinishing of needle roller bearing is required to understand somewhat, the conditions of various spare parts need to meet the specified requirements, such processing results with inner ring needle roller bearing can be satisfactory.
